Abstract: An information providing apparatus for vehicle has a remaining capacity detecting section 110 that detects a remaining capacity of a battery; a power consumption amount detecting section 130 that detects a power consumption amount of the battery; a power consumption amount history generating section 130 that generates a power consumption amount history on the basis of the power consumption amount detected by the power consumption amount detecting section 130; a charge necessity judgment information generating section 130 that generates, on the basis of the power consumption amount history generated by the power consumption amount history generating section 130, charge necessity judgment information which is information for user's judgment about whether or not charging of the battery is necessary; and a providing section 150 that provides information of the remaining capacity of the battery and the charge necessity judgment information with these information correlated with each other to the user.

Abstract: A vehicle charging facility information acquisition system has comprising an acquisition component and a charging record information storage component. The acquisition component is configured to acquire, from a plurality of vehicles, information pertaining to a vehicle charging facility as charging record information when the vehicles use the vehicle charging facility, with the information including at least vehicle charging facility position information. The charging record information storage component is configured to store the acquired charging record information in a charging record information database.

Abstract: When a change occurs between a previous traffic condition based on traffic information provided previously and the current traffic condition, a control unit of a vehicle-mounted device performs control such that traffic information is acquired from an external device via wireless communication. A comparison of current vehicle traveling conditions and previous vehicle traveling conditions can also be used to determine whether traffic information should be updated.

Abstract: A device and method to enable the prediction of a traffic jam even when the road environment changes. On the basis of up-to-the-minute, i.e., current, traffic jam information and changes from the preceding traffic jam information, the current traffic state is estimated. On the basis of the up-to-the-minute traffic jam information and the current traffic state, the current traffic jam degree is predicted. The results can be used in a conventional navigation method and apparatus to plot driving routes for a vehicle.

Abstract: A navigation system comprising an apparatus and method for navigating a vehicle along a detour route when appropriate. A destination is set, and the current location, or site, is detected. Guiding is performed along an optimum route from the current location to the destination. When a traffic obstacle that requires a detour from the optimum route is detected, a detour to the destination that detours the traffic obstacle is searched. The detour is a route having the shortest time and/or the shortest distance from the current location to the destination. Guiding is performed for the detour route at a site located a prescribed distance from a branching point where branching is to be made from the optimum route to one of at least two detour routes.

Abstract: Along with displaying on a map a sign which indicates the type of a traffic event at the side of the traffic lane upon which the traffic event has occurred, the sign and the position of the traffic event are displayed upon the map in a state of being connected together by a line or by a drawing.

Guiding is performed along an optimum route from the current location to the destination. When a traffic obstacle that requires a detour from the optimum route is detected, a detour to the destination that detours the traffic onstacle is searched. The detour is a route having the shortest time and/or the shortest distance from the current location to the destination. Guiding is performed for the detour route at a site located a prescribed distance from a branching point where branching is to be made from the optimum route to one of at least two detour routes.
